At the Cooler Synchrotron COSY/J\"ulich spin-correlation parameters in elastic proton-proton ($pp$) scattering have been measured with a 2.11 GeV polarized proton beam and hydrogen atomic target. We report results for ${A}_{NN}$, ${A}_{SS}$, ${A}_{SL}$ c.m. angles between $30\ifmmode^\circ\else\textdegree\fi{}$ $90\ifmmode^\circ\else\textdegree\fi{}$. Our data on ${A}_{SS}$---the first measurement of this observable above 800 MeV---clearly disagrees predictions available $pp$ phase-shift...
Excitation functions of the spin correlation coefficients ${A}_{\mathit{NN}}({p}_{\mathrm{lab}},{\ensuremath{\theta}}_{c.m.}),{A}_{\mathit{SS}}({p}_{\mathrm{lab}},{\ensuremath{\theta}}_{c.m.})$, and ${A}_{\mathit{SL}}({p}_{\mathrm{lab}},{\ensuremath{\theta}}_{c.m.})$ have been measured with polarized proton beam Cooler Synchrotron an internal atomic target. Data were taken continuously during acceleration for momenta ${p}_{\mathrm{lab}}$ ranging from 1000 to 3300 MeV/c (kinetic energies...
Starting from a characteristic biinvariance property of Higgs potentials in gauge theories with nonunitary parallel transporters, we explain how quarks different flavor can acquire masses by spontaneous symmetry breaking and what is the difference between colour flavor. We present theoretic model where Cabbibo-Kobayashi-Maskawa matrix becomes computable principle. The lives on five dimensional space time two four boundaries R L small distance d apart. Right handed leptons live left L....
